Hearing Loss
Causes for hearing Loss:
-
High Volume (Sound Pressure Level / Decibels)
- 85 dB+ for long periods = risky
- (e.g., loud traffic, hair dryers, busy restaurants)
- 100+ dB for short bursts = damaging
- (e.g., concerts, clubs, power tools, headphones at max)
- 85 dB+ for long periods = risky
-
If they’re forced to vibrate too hard or too often, they bend, break, and die — permanently
-
Duration of Exposure
Volume | Safe Listening Time |
---|---|
85 dB | ~8 hours |
95 dB | ~1 hour |
105 dB | ~5 minutes |
-
Headphones
- No air to diffuse the pressure, so inner ear takes the full hit
- People often turn them up to overcome noise, increasing risk
-
Acoustic trauma: Explosions, gunshots, firecrackers (>120–140 dB)
The inner ear hair cells (in the cochlea) vibrate to detect sound
- Tinnitus (ringing) can be an early sign of damage.
- Poor recovery time between exposures increases risk.
Risk Mitigation
Use speakers when possible
Avoid Cotton Swabs
- Don't push wax in; it can damage your eardrum or canal.
Let Ears Recover
- After loud exposure, give your ears 12-24 hours of quiet.
Use vented or high-fidelity earplugs (like Loop, Etymotic, or Alpine) — they reduce harmful sound without totally muting your environment.
